A case of death associated with ingestion of liquid windshield-washer detergent

We report an autopsy case of a death associated with ingestion of liquid windshield-washer detergent. The deceased was a 49-year-old man who was found dead on a road near his truck. A bottle of liquid windshield-washer detergent containing an anionic surfactant and methanol was found under the passenger seat of the truck. At autopsy, slight abrasions and bruises were observed on his body. The small intestine contained dark greenish-brown mucoid matter with abundant froth. The mucous membranes of the esophagus, stomach and superior small intestine showed extensive necrosis, erosion, hemorrhage, edema and congestion. Using the methylene blue method to examine the contents of the small intestine, the presence of an anionic surfactant was indicated. We conclude that the cause of death was ingestion of liquid windshield-washer detergent.
